根据薄壁筒体两端面切削加工的特殊要求,介绍了专用工装—薄壁筒体两端面切割设备的结构组成、工作原理、传动比计算及使用效果。
4) secant facet
切割平面
1.
In mathematics,an ellipsoidal surface can be approximated by a series of continuous secant facets,each of which passes through four corner points of corresponding grid formed by two geodetic parallels and two meridians and is taken as mapping plane.
以规则的经纬网格为单元,以每4个网格角点所构成的平面来切割并逼近椭球面,椭球面上同纬度的点子均以椭球短轴上的相应点为投影中心投影到各切割平面,采用这种类似楔形的投影方式,将减小长度投影变形的最大值,并使相邻图幅之间保持空间连续。
2.
In this projection mode, the ellipsoidal surface can be approximated mathematically by a series of continuous secant facets which are all isosceles trapezoids.
本文主要采用了两种投影方式将椭球面上的各点按经纬网格投影到相应的切割平面上：楔形投影和按各点的椭球面法线进行投影。
